Here’s another cool opening video. This one is on the Danish. Black’s Queen sac was memorable when I first saw it and it sticks with me to this day.

I think you linked the wrong video - it doesn’t have anything about the Danish or any Queen sacrifice. Instead it covers a few Benoni variations.
Oops! Thanks for that. I fixed it and the link works now.
